How Does Micro Switch Dimension Affect Its Features

Selecting the proper dimension micro switch is of great importance for application as the dimension of micro switch is directly relevant to its features, including circuit range, travel and operation force. For example, the minimum micro switch dimension in the market is 0.5 inches * 0.236inch * 0.197inch (L*W*H). Though the miniature micro switch can be used to inspect the compact circuit situation, it can only cut off 0.1A to 0.3A current, and the travel is short. If the circumstance or environment requires a larger current, the giant-size micro switch has to be needed. Take the oil tank, for instance; the micro switch to inspect the liquid’s level position requires long travel and enduring a significant current.

And regarding the liquid switch application, the micro switch needs to drive the pump directly, which has to apply electrical rating 125VAC or 250VAC and the current 20A or 25A big micro switch.   

If the micro switch dimension is small, its travel and current it can cut off will be small. In addition, the micro switch design will affect its operation force. In the ideal case, the engineers need a micro switch with low operation force but high current.   

But in reality, we have to make concessions between them. When provided with a significant current, you must keep good contact. The micro switch requires a stronger spring, making the operation force more robust and prominent. Currently, the market’s most significant size micro switch is 1.94inch * 0.69inch *1.3inch (L*W*H). This dimension will significantly affect its features or functions.
